RISER.

To all whom t may concern.'

Be it known that I, ARTHUR M. SMITH, a citizen of the United States,residing at the city and county of San 'Francisco and State ofCalifornia, have invented new and useful Improvements in Risers, ofwhich the following is a specification. v

This invention relatesv to a riser for use in bed structures. v

The object of the invention is to simplify and improve the constructionand operation of a device of this character. In carrying out this'objectI make use of a sheet metal riser detachably fitted upon the side railof the bed structure and extending upwardly to form a support for thetransverse rail to which the spring fabric is secured. The riser is ofsimple and inexpensive construction and is readily and easily attachedto the side rail and permits the anchor rail to be quickly and easilyattached thereto. The riser, while constructed of comparatively thinmaterial, is so shaped as to afford ample support and resistance to theweight imposed thereon by the spring fabric. A novel and inexpensive wayof securing the head piece to the riser is also embodied in the presentinvention.

One form which my invention may assume is exemplified in the followingdescription and illustrated in the accompanying drawings, in which- Fig.1 shows a side elevation of a folding bed fitted at each end with ariser built in accordance with my invention.

Fig. 2 shows a side elevation of a part of the head of the bed.

Fig. 3 shows a rear elevation of the part shown in Fig. 2.

Fig. 4 shows a plan view of the sheet of material from which the riseris constructed.

In the present form of the device a side rail 10 is fitted at each endwith a riser 11. On the top of each riser is an angle bar 12 whichserves as an anchor for spring fabric 13. In the structure shown, theouter end of the frame is supported by a foldable foot piece 14 and theinner end carries a jointed head piece consisting of a lower stationarytubular member 15 and a hinged upper portion 16. The head of the bedframe is piv- -otally mounted upon brackets 17 for folding movement. Itis obvious, however, that the riser with which the present invention isparticularly concerned may also be used in connection with beds otherAthan folding' beds- The riser consists of a piece of sheet metal ysiderail and prevent spreading of the side walls and to retain the riser invplace. A riser is thus formed which is anchored at its lower portion andhas a vertical flat wall at each side and a convex wall at the enddisposed towards the spring fabric. This convex wall will serve toresist endwise the load imposed thereon by the spring fabric. The outerend of the riser is left open. The edge of each side wall at the openend has a lug 22 to enter an opening in the anchor rail 12 for retainingthe latter in place.

On one of the side walls, near the bottom thereof, is an elongated tab23 adapted to be extended across the open face of the riser and toreceive a bolt 24 for fastening the lower end of the stationary tubularmember 15 in position thereon. This tubular member is also connected tothe anchor rail 12 by means of a bolt 25 which extends through saidtubular member and has/its head lying in a slot 26 formed in the saidanchor rail. The slot in the anchor rail permits the bolt 25 to bearranged on the tubular member before the parts are assembled and thebolt can thereafter be tightened by means of a nut 27 disposed at theoutside of the tubular member. The position of the bolt 24 is such as topermit of its being inserted and connected up after the parts areassembled.

Access to one end of the bolt 24C may be had through the open end of thetubular member 15, whereas the other end of the bolt is accessiblethrough the open face of the riser. If this bolt were accessible onlythrough the open end of the tubular member 15, then it would benecessary to tap it onto the riser, which would require a heavier pieceof meta] than that from which the riser is made, thus making itimpossible to use the integral arrangement shown at 23.

Various changes in the construction and arrangement of the several partsherein shown and described may be employed without departing from thespirit of my invention as disclosed in the appended claims,

Having thus described my invention, what I claim and desire to secure byLetters Patent is zl. In a bed structure, a side rail, a sheet metalriser having itskbody portion bent into the form of U when viewed inplan, legs integral with the body portion and extending around the rail,the ends of said legs being inturned to engage the sides of a slotformed in the rail. f

2. In a bed structure, a side rail, a sheet metal riser comprising abody portion U-shaped in plan, legs formed integrally with the sideWalls'of the riser extending around the side rail and angular portionson the ends of the legs adapted to enter a slot in the bottom of thesiderail.

3. In a bed structure, a side rail, a sheet metal riser comprising aybody portion U-shaped in plan, legs forming a continuation of the sideWalls of the U-sliaped structure extending around the side rail, meansfor detachably securing the ends of the legs in a slot formed in therail and an anchor rail `for supporting the spring fabric arranged uponsaid riser, said riser having the convex portion of the U-shapedstructure disposed between the anchor rail and side rail so as to resistendxvise the tension of the spring fabric.

4i. In a bed structure, a side rail, a sheet metal riser comprising abody portion U-shaped in plan disposed above the rail, the side Walls ofthe body portion being extended around the rail, an anchor rail for thespring fabric carried on the U-shaped structure, a tab formed integrallywith one of the side Walls and extending across the open face of theU-shaped structure, a post adjacent the open face of the riser and meansconnected with the tab and the anchor rail for securing the post inposition.
